lM PROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 204,361, dated May 28, 1878 application filed March 30, 1878.

To all whom it may concern:

Be it known that I, FRANZ N I'ISCHMANN, of Flatonia, in the county of Fayette and State of Texas, have invented a new and valuable Improvement in Plows and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of my plow. Fig. 2 is a bottomplan view, and Fig. 3 is a perspective view, of a portion thereof.

The nature of my invention consists in the construction and arrangement of a plow, as will be hereinafter more fully set forth.

The annexed drawings, to which reference is made, fully illustrate my invention.

A represents the land-side, formed with the point B and share 0 either in one piece or separate, and fastened together. From the outer side of the share 0 extends a curved flange or bar, D, rearward and upward, as shown, and this bar is provided with a rod, a, which projects toward and is riveted or otherwise permanently secured to the land-side A. Previous to fastening this rod to the land-side it is cut with exterior screw-threads, and aunt, b, placed thereon. On this rod a next to the land-side is placed the hook of a hooked rod, d, and the nut b is then run up against it to fasten the same. This rod d passes upward through an eye, 0, formed upon an arm, A, of the land-side, and then passes up through the plow-beam F, a thumb-nut, f, being screwed on the upper end of said rod. Another rod, h, is fastened by a bolt to the land-side A in rear of the rod a, and this rod h also passes upward through the plow-beam F, and a nut, t, is screwed on said rod against the under side of the beam. By these means the beam F can be adjusted up and down on the rods d and h, so as to regulate the depth of the plowmg.

At the rear end of the plow-beam, in a recess in the outer side, is placed the handle G, and the lower end of said handle is fastened by a bolt to the heel of the land-side. The handle G is fastened to the beam by a rod, m, which is curved upward and outward, as shown, and then passes through the other handle, G, and thumb-nuts n n are placed on said rod, one on each side of the handle. The lower end of this handle G is fastened by one or more bolts to the upper end of the flange or bar D.

By means of the rod m and the thumb-nuts n n the handles can be adjusted so as to regulate the width of the furrow or cut.

H represents the mold-board of the plow. This mold-board is at its lower edge provided with two projecting lips, pp, and a pin, 8. The lips 17 19 extend under the upper edge of the share, while the pin 8 projects into'a hole on the flange or bar D at or near the lower end.

On the back of the mold-board, at or near the upper end, is a lug or ear, t, to which is pivoted the forked end of a lever, I. This lever is bent, substantially as shown, and passes through an eye in a post, J, on the handlelG', and its upper end is held in a ratchet-bar, L, also secured to said handle.

It will be seen that the mold-board is adjustable at any angle with relation to the share, and thus adapts the plow to any kind of soil.

What I claim as new, and desire to secure by Letters Patent, is-- 1. In combination with a plow and plowbeam, the rods 61 and h, connected directly to the land-side of the plow, and passed upward through the beam, and provided, respectively, with the thumbnut h and nut iabove and below the beam, as and for the purposes herein set forth.

2. The combination, with the share 0 and perforated bar D, of the mold-board H, pro vided with the lips 17 and pin 8, and a lever or handle for adjusting the mold-board, substantially as herein set forth.

3. The combination of the movable moldboard H, lever I, perforated post J, and ratchet-bar L, substantially as and for the purposes herein set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

FRANZ NITSCHMANN.
